Replaced Two Old Units – Cools Better and Cut My Bill in Half! I replaced a loud, inefficient window AC and a struggling portable unit in my sunroom with this single mini-split. The difference is night and day. The cooling is faster, more even, and MUCH quieter. My sunroom is now the most comfortable room in the house. The best part is the savings: my summer electric bill for that part of the house is literally half of what it used to be. It cools more effectively while using less energy. The installation was an upfront cost, but the performance and monthly savings make it worth every penny. Highly recommend for effective and efficient cooling.

Excellent unit. Have used in both summer and winter at this point in Kansas. Cooling is great but heating is a little lacking for ~1,000 sf. Although not covered in the installation manual, I did evacuate the system which did require an adapter to fit the orifice. Unit produced very little noise in normal operation and was pretty easy to install. The remote works great but the icons could should be changed for more clarity. A fire sign for heat versus a sun would be a little less confusing to my wife.

I did a ton of research on mini-splits and their efficiency numbers (SEER/HSPF), and I can say this one actually delivers. The key is the inverter tech. Instead of just blasting at 100% and then shutting off (which is what my old unit did), it smoothly adjusts its power. This not only saves a bunch on energy but also keeps the temperature perfectly steady – no more annoying hot or cold swings. The cooling is fantastic – it gets cold fast and really takes the stickiness out of the air. Even more impressive is the heat. We’ve had it down in the 30s (°F) here, and it’s kept us perfectly warm, all while costing way less to run than the old gas heater I used to fire up in this room. I can see the difference on my power bill every month. Just a heads up, you’ll need to get it professionally installed. But once it’s in ，for sheer performance and how much it saves you, it’s absolutely top-tier.

This 12,000 BTU mini split works perfectly for my 700 sq.ft room. It cools quickly in summer and provides reliable heat in colder days. The unit is quiet, energy efficient, and my power bill hasn’t gone up much. Installation was manageable with the included kit, though I hired a pro for the final hookup. Very happy with this purchase!

Just installed it and it is not coming on and nothing is working and a professional electrician installed at a professional HVAC and I’m not able to get any response back. I have called to the troubleshooting process. There is something wrong with the unit I need to on the board. I’m sure it’s a glitch in there somewhere but I have a brand new unit paid $1500 installation and it’s not working.

Fairly easy hook up. Instructions and template does not indicate which side the drain and wires come out so you have to look at the back of the unit before you drill a hole. It is not universal for right or left. You have to go with what the unit has on the back. I ended up drilling two holes because I just followed the template. Other than that, it’s been running great and it was a fairly easy install.

I haven't used it yet this winter, but it's pretty good. It runs quietly, has a simple and elegant appearance, and I'm very satisfied with the overall experience. It's great value for money.

I prioritized finding a quiet AC for my home office/bedroom, and this unit delivers beyond expectations. On the highest cooling setting, the air is seriously cold and effective, yet the indoor unit is barely audible—just a gentle whoosh of air. I don’t have to turn up the TV volume or pause calls. I’ve also noticed it cycles less frequently than cheaper models, which I believe contributes to its energy efficiency. It maintains the set temperature steadily without constant noisy startups. The cooling is powerful yet non-intrusive. For light sleepers or anyone needing a peaceful, cool environment, this is a 10/10.
